PAPER-CUTTING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 242,551, dated June 7, 1881.

Application filed April 11, 1881. (No model.)

To all whom it may concern:

Be it known that I, EDWARD L. MILLER, of the city of Philadelphia and State of Pennsylvania, have invented certain Improvementsin Paper-Cutting Machines, of which the followin g is a specification.

Paper-cuttin g machines in general consist of a knife to cut the paper moved by proper mechanism, a clamping-bar to hold the paper in place while it is out, and a gage by which the proper position of the paper is determined.

It is desirable that the clamping-bar shall be wide at its base, so as to take a firm hold of the paper without wrinkling or disturbing it, as it will do, more or less, if narrow; but at the same time, with a wide clampingbar, it is impossible to make the narrow cuts which are frequently necessary, because the width of the paper to be out is determined by the distance between the knife and the gage, and the clamping-bar intervenes between these two. It is to relieve this difficulty, which has not been done heretofore except by the use of complex devices, and to secure in one machine, without complication of parts, the ad vantage of a wide bearin g and the capacity of a narrow cut without reduction of thickness of the paper, that I have constructed the device represented in the drawings,in which Figure 1 is a back view of a paper-cutter, omitting the knife, which is shown in Fig. 3, but showing the gage A and the clamping-bar B, in which is a recess for the removable piece 0, shown separate in Fig. 2.

In making narrow cuts the machine is used as shown in Fig. 1, but in ordinary work it is used as shown in section in Fig. 3, in which the removable piece 0 is shown in its place in the clamping-bar B, forming with it a broad base to hold the paper firmly while it is cut, the lift of the bar and the capacity to receive a thickness of paper being the same in either case.

It will be observed that the clamping-bar is constructed as the same part of similar machines has been heretofore ordinarily constructed, with the exception that it partlyconsists of or contains the removable piece 0, which may be placed in a recess in the clamping-bar, as shown, or may be held in place upon its flat surface, in which case the entire clamping-bar is made narrow, with projections to support the movable piece. With this piece in place the clamping-bar holds the paper firmly with a broad surface, but the machine is not capable of cutting paper of a width less than that of the whole bar; but when this piece is removed the gage may be brought up toward the knife,' and the paper may be cut of a much less width,

and these results are attained by the removal or replacementof this single piece from or upon the clamping-bar, with no change in any other part of the machine, and with no diminution of capacity as to thickness of paper to be held and out.

I claim as my invention In combination with the knife and gage of a paper-cuttin g machine, the clamping-bar furnished with the removable piece 0, substantially as and for the purpose specified.
